The Lowrider concrete trowel from MBW features an engine that mounts to and tilts with one of the trowel’s rotors as a unitary assembly, which eliminates approximately 50 percent of components in the drive train of frame-mounted engine designs, and is designed to improve belt alignment and simplify belt replacement. A lower center of gravity results in less rocking motion during operation, as well as flatter floors, the maker says. www.mbw.com/
